Six initial conditions and nine radiation pressure para- meters per satellite were determined. No pseudo-stochastic pulses have been introduced up to now. - So far only receivers providing dual frequency GPS and GLONASS or dual fre- quency GLONASS measurements were included in the solution. - The daily orbit results stem from the middle day of a 5-day arc. - The satellite clock values included in the precise orbit files are broadcast clock values for the GLONASS satellites (no improvement done so far) and precise CODE estimates for the GPS satellites. - The following sites are constrained to their ITRF97 coordinates: - GODZ 40451M123 (Greenbelt, USA) - KR0G 10422M001 (Kiruna, Sweden) - OS0G 10402M004 (Onsala, Sweden) - YARR 50107M006 (Yaragadee, Australia) - ZIMZ 14001M005 (Zimmerwald, Switzerland) ------------------------------------------------------------------------------- FILES SENT TO GLOBAL DATA CENTERS: ------------------------------------------------------------------------------- COX1055N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10557.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 86 104 344119 9691 1.2 87 104 339521 9841 1.2 88 102 339021 9615 1.2 89 101 325485 9296 1.1 90 101 329370 9348 1.1 91 100 324910 9230 1.1 92 99 319123 8744 1.1 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101 107 108 109 111 113 115 122 ------------------------------------------------------------------------------- 86 6 4 6 5 7 8 7 4 87 7 7 8 7 3 6 4 5 88 3 4 3 6 6 4 3 3 89 4 6 7 7 7 6 5 3 90 5 5 7 5 5 6 5 4 91 4 3 7 6 8 5 2 2 92 4 3 8 6 9 3 3 3 ------------------------------------------------------------------------------- ALL 5 5 7 6 7 6 5 4 ------------------------------------------------------------------------------- Remark: These RMS values may be too optimistic, because we fit the middle days of 5-day arcs with a 7-day arc. ------------------------------------------------------------------------------- WEEKLY COORDINATE COMPARISON OF 1-DAY (Z1) SOLUTIONS ------------------------------------------------------------------------------- TOTAL NUMBER OF STATIONS: 23 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- BIPD 10094M001 7 PPPPPPP 7 9 40 BORG 12205M004 7 PPPPPPP 6 9 26 CRAR 66001M004 6 PPPP PP 12 15 14 DAVR 66010M001 7 PPPPPPP 11 14 11 DLFT 13502M006 6 PP PPPP 1 2 5 GATR 6 P PPPPP 4 9 10 GODZ 40451M123 1 P - - - CONSTRAINED GOPE 11502M002 7 PPPPPPP 2 3 5 GRAB 11001M004 7 PPPPPPP 3 4 5 KR0G 10422M001 7 PPPPPPP - - - CONSTRAINED LHAZ 21613M002 5 PPPPP 6 15 9 MTBG 11030M001 7 PPPPPPP 2 3 4 MTKA 21741S002 6 P PPPPP 9 6 13 NPLC 13234M001 6 PPPP PP 15 22 38 OS0G 10402M004 5 PP PPP - - - CONSTRAINED REYZ 10202M003 7 PPPPPPP 2 3 8 THU2 43001M002 6 PPPPP P 1 6 8 TSKA 21730M003 7 PPPPPPP 11 14 12 VSLD 13502M008 5 PPPPP 3 7 14 WTZZ 14201M014 5 PPPPP 3 2 8 YARR 50107M006 7 PPPPPPP - - - CONSTRAINED ZIMJ 14001M006 6 PPPPPP 2 1 4 ZIMZ 14001M005 7 PPPPPPP - - - CONSTRAINED -------------------------------------------------------------------------------
